Downloaded premade deck; all cards in one category have same ID

Downloaded premade anki deck pepper sketchy pharm that separates cards based on videos they are from. For instance, for one grouping (subdeck/tag) (example 4.1 antiarrhythmic drugs), it shows as having 21 cards or so but when I answer a card then I am done with my reviews. Checked on browse and it looks like each card has like 21 questions and this is repeated 21 times. In each case, the card ID is different but the note ID is the same. No idea how to be able to review all 21 questions as separate cards. If anyone can help me I’d be so grateful!!
